Abstract

The invention discloses a long-slab-span steel beam cast-in-situ floor formwork system, which comprises a floor template, an adjustable truss and an adjustable placement support seat for supporting the adjustable truss, wherein a grille is laid on the adjustable truss; the floor template is laid on the grille; the adjustable placement support seat is arranged on a lower flange of a transverse H-shaped steel beam; and the adjustable truss is a telescopic combined truss and is connected with the upper end of the adjustable placement support seat. Compared with the conventional normal truss formwork system, the long-slab-span steel beam cast-in-situ floor formwork system provided according to the invention has the advantages of adjustable span, adjustable height and suitability for different beam heights; the adaptability of the truss is greatly improved; and the formwork cost is greatly lowered.

Description

technical field [0001] The invention relates to a building system, in particular to a formwork support system for cast-in-place floor slabs with large span steel beams. Background technique [0002] Usually, the floor support adopts full-scale scaffolding, and the scaffolding generally adopts steel pipe scaffolding or wrist buckle scaffolding, all of which need to be connected by vertical and horizontal rods to ensure stability. The setting of horizontal braces and scissor braces will bring problems such as inconvenient construction passages, cumbersome assembly and disassembly, increased turnover materials, and increased costs. [0003] In order to solve the above problems, the Chinese utility model patent with the announcement number CN2617859 and the name "truss-type support formwork system" discloses a truss-type support formwork system. 1. Fix a number of wooden joists vertically arranged on the truss and panels laid on the truss and the wooden joists. The use of trus...
